Entry #1 and #2 are so similiar (to my eyes!) that I had to keep flipping back and forth to choose and, then I would change my mind. So, that's obviously a minor detail. What can I say--this logo is clean, professional, not too cutesy, the magnifying glass is unobtrusive, the font is lovely. I failed to mention on the main description that I visualize a logo that has a "hint of sensual or borderline sexy" and I would have never thought a logo with a magnifying glass/object could get close to achieving that. I've seen alot of P.I. logos with a magnifying glass and they just look cheesey-but you've pulled it off.
P.S. I happen to have a gigantic (wall-size) wooden magnifying glass with huge clock hands inside that hangs on my office wall. (No, it's not turqouise!)
I'm really glad that you like my work. I appreciate it much. And if you want to ask me something, don't be hesitate to tell... I will make a quick response, and do my best.
